TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N0.-498,100, dated May 23,1893.

Application filed May 27, 1892. Serial No. 434,566- (No model.) i

To all whom it may concern:

Be it known that I, EDGAR HENRY BERRY, of New York city, in the countyand State of New York, have invented a new and Improved Type-WVritingMachine, of which the following is a full, clear, and exact description.

The invention relates to that class of typewriting machines carrying thetype on movable arms swinging to a common point.

The object of the invention is to provide a new and improved typewritingmachine,which is simple and durable in construction, not liable to getout of order, and. arranged to print two different type characters bythe use of the same key.

The invention consists principally of a key lever connected with twotype bars and having a changeable fulcrum.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a transverse section of the im provement on the line 1-1 ofFig. 3. Fig. 2 is a like view of the same in a different-position. Fig.3 is a sectional front view of the same on the line 3-3 of Fig. 1. Fig.4 is a similar view of the same in a different position; and Fig. 5 is asectional side elevation of part of the shifting device. x

As shown in thedrawings only one key, its lever, and the two type barsoperated from this lever, are represented, it being understood that alike arrangement is made for the keys representing various characters inthe machine. The key-A is pivotally connected with the key leverB'supported at its rearend on a fulcrum 0 attached to or forming part ofthe frame D. 7

Near the front end of the key lever B and on top of the same, isarranged a longitudinally extending bar E adapted to form, inconjunction with the second bar F arranged below the said key lever, afulcrum for the latter. The bar F is connected at its ends with a secondbar F extending parallel to the bar F,but arranged above the key leverB, as will be readily understood by reference to Figs. 1 and 2. The twobarsFand F have their end I connections F and F pivotally connected witharms G and G respectively, projecting from a shaft H mounted to turn insuitable bearings on the frame D, the said shaft extending under the keylever B. The swinging motion of the bars vF F is limited by stops Fprojecting from the ends of the frame D. Ina

like mannerthe inward swingingmotion of the arms G is limited by stopsGr also projecting from the ends of the frame, see Figs. 3 and 4. Now itwill be seen that when the connected bars F and F are in the positionshown in Fig. 1, then the bar F is located directly above the fixed bar0, the sharp' edge of the bar resting on top of'the lever B, sothat thelatter swings from the said bar F and the fixed bar 0 as the fulcrum.When the shaft I H is turned'so that the arms G and G swing upward untilthey strike against the stops G see Fig. 2, then the bar F rests againstthestops F while the other bar F is moved into contact with the bottomof the lever B directly under the fixed bar E. The two bars E and F thenform the fulcrum for the lever B near the front end connected with thekey A.

The key leverB is connected by links land I with the type bars J and Jrespectively,

each carrying a type moved to the same point when the type arms swingupward, as illustrated in dotted lines in Figs. 1 and 2. The

connections of the links I and I with the lever B are on opposite sidesof the shaft H; that is, the link I is pivotally connected with thelever B near the rear fulcrum, while the other link I is connected withthe lever near the front fulcrum formed by the bars E and F. The link Iis composed of the rods Band 1 connected with each other bya turn buckleI in such a manner that the rod l screws in the upper end of the turnbuckle, while the rod 1 is loosely connected with the lower end 5 of theturn buckle and is formed with a collar I abutting against the underside of the said turn buckle. The link I is similarly constructed andcomposed of rods I and I connected with each other bya turnbuckle I 'I00The rod l is providedwith a collar I engaging the inside of the lowerend of the turnbuckle 1 so that when the lever B swings upward, the rod1 passes loosely upward in the turnbuckle without pushing the rod 1upward but when the lever B swings downward the collar 1 engages thelower end of the turnbuckle I and consequently exerts a pull thereon sothat the rod Pimparts a swinging motion to the type arm J to cause thetype of the latter to make the impression. When the lever B is presseddownward with the parts arranged as in Fig. 1, the rod 1 of the link Islides loosely in its turn buckle I so-that the rod 1 remains at astandstill and consequently does not affect the arm J, but when thelever B swings upward with the parts arranged as in Fig. 2, then thecollar 1 abutting against the under side of the turn buckle I pushes thelatter and the rod 1 in an upward direction so as to impart a swingingmotion to the type arm J to cause the type of the latter to make theimpression. Now, it will be seen that when the several parts are in theposition shown in Fig. 1; that is, the fulcrum of the lever B is nearthe rear end of the same between the bars C and F and the key A ispressed, then the type arm J remains at a standstill while the link Ipulls on the type arm J, thus causing the type end of the latter toswing upward to make an impression. hen the shaft H is turned to changethe fulcrum of the lever B to the front end of the same, as shown inFig. 2, and the key A is pressed, then the rear end of the lever Bswings upward and gives a push to the link I, which by its connectionwith the type arm J, causes the type end of the latter to swing upwardto make the impression, while the other type bar J remains at astandstill, owing to the sliding of the rod I of the link I in the turnbuckle 1 Thus, according to the position of the fulcrum of the lever B,either of the type bars J or J, with which the said lever is connected,is actuated to make an impression, while the other remains at astandstill.

In order to impart a turning motion to the shaft H to obtain the desiredposition of the fulcrum for the lever B, the following device isprovidedz-On the shaft H, at its ends, are formed the arms G and Gstanding approximately at right angles to the arms G and G respectively.The arms G and G are pivotally connected with levers K and Krespectively, fulcrumed at K and K on the ends of the frame D of thetypewriting machine. The front ends of the levers K and K are pivotallyconnected with keys L and N respectively, located in the rear of thefirst row of ordinary keys A and on the sides of the machine, as will bereadily understood by reference to the drawings. The front ends of thelevers K and K are formed on their under sides with notches K and Krespectively, adapted to be engaged by a longitudinally extending plate0, hung at its middle on a spring P supported with its upper end on asuitable bracket arranged on the frame D. 011 the top of the plate C)and at the middle of the same is arranged a segmental offset 0 engagedby the forked end Q of a shifting lever Q, pivoted on the bracket forthe spring P and adapted to be shifted by the operator, either from theposition shown in Fig. 3 to the one illustrated in Fig. 4, or viceversa, so as to depress either end of the plate 0 to hold up, by theother raised end of the said plate, the respective lever K or K, seeFigs. 3 and 4. When the shifting lever Q is in the position illustratedin Fig. 3, then the left-hand end of the plate 0 is in an uppermostposition, thus holding the lever K and its keyL raised, as shown in Fig.1, whereby the shaft H is held in the position indicatedin the said Fig.1, that is, the arms G and G are in the lowermost position, holding thebar F over the lever B directly above the fixed bar 0, so that thefulcrum of the lever B is at the rear end of the same. Now when the keysA are pressed, only the type arms J connected with the front ends of thelevers B are actuated, the said type arms J being preferably formed withcapital letters representing the upper case. When the shifting lever Qis moved to the position shown in Fig. 4, then the righthand end of theplate 0 swings upward, thus imparting a swinging motion to the lever K,whereby the position of the shaft His changed; that is, the arms G and Gswing upward into the position shown in Fig. 2. The fulcrum for thelevers B is now between the bars E and F, and when one of the keysA ispressed the type arms J are actuated, as before described. These typearms J carry small letters and represent the lower case. When the deviceis in this position, only small letters are printed, but when it isdesired to print a capital letter, then the operator temporarily pressesthe key L so as to impart a downward swinging motion to the front end ofthe lever K, thereby changing the position of the shaft H whereby thefulcrum for the levers B is made at the rear ends of the same betweenthe fixed bar 0 and the bar F. As soon as the operator now presses thedesired key, the type arm J, carrying the desired capital letter, makesan impression, and as soon as this is done, the operator releases bothkeys A and L so that the spring P returns the plate 0 to its formerposition, shown in Fig. 4, thus reversin g the position of the shaft Hto that it previously had, to permit of printing small letters only whenthe keys A are pressed. In a like manner when the upper case only isused; that is, when the plate 0 is in the position shown in Fig. 4, andit is desired to print a small letter, then the operator temporarilypresses the key N to change the position of the shaft H to throw thefulcrum for the lever B to the front end between the barsE and F. Assoon as the desired small .letter has been printed, by pressing therespective key, the operator releases the pressure on the key N so thatthe spring P returns the plate 0 to its normal position. It isunderstood that the .forked end Q forms the fulcrum for the plate 0 toswing on when either of the keys L and N is pressed, and the said leverQ is in aleft or right-hand position. It is further understood that whenone of the keys is temporarily pressed to change from upper case tolower case, then the spring P tilts sufiicientlyto permit pressing thatend of the plate downward to change the position of the shaft H, asabove described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
